Used Buick in Peoria, IL

There are 142 used Buick listings on CarsPeoria right now, gathered from dealership websites around Peoria, East Peoria, Pekin, Morton, Washington, and nearby Illinois towns. Each card shows the photo the lot published, the asking price, the odometer reading, and which dealer has the Buick — then you open that dealer’s own listing in a new tab to confirm it is still for sale. Buick crossovers and sedans around here often share a lot with GMC or Chevrolet, so the same Saturday trip can cover more than one badge. We do not sell Buick vehicles — when you are ready, deal with the listing dealership on price, history, and paperwork.
